Always a tough subject to answer! Let’s see…at this time…
Caveat Up Front: Filling out this list yearly would probably get different results most of the time.
One Soap: My clown puke tub - hell if I remember what’s in it but it’s a bunch of good stuff and it’s definitely the best soap I have.
One Post Shave: My homemade witch hazel and aloe blend - two applications after every shave, never fails.
One Razor: Colonial “Armored” v1 Brass General AC SE - My grail razor for sure.
One Brush: Yaqi Rainbow w/ pony synth knot - Grail knot for sure, has never failed to help make superb lathers; the handle is quite ergonomic as well.
One Blade: Schick Prolines - Smoothest, most comfortable AC blade I’ve tried so far.
One Cologne/Fragrance: YSL Rive Gauche - Knockout, anytime year-round frag.
One Pipe/Cigar: My Kirsten “MX” Goldtone pipe - Even if I didn’t smoke it…it’ll last forever with even minimal care and it looks cool.
One Drink: Coffee - nuff said.
One Wildcard (for something you just want to add): My HK P3000SK (9mm) - inevitably in such a scenario, there’s going to be times where it comes down to who’s got the wits and better tools; other tools I could construct with some effort.
